Hello,

I am a bit confused with the Canna guide on their website. I use canna bio nutes and it says on their website that if they are being used with their Bio organic soil then the ph of the solution does not need to be corrected however when I test my solution is usually 4.8-5 which seems a bit low so I’m not sure if I need to correct it or just leave it as they say?
